Groundwater vulnerability in the Athabasca and Cold Lake oil sands regions: gaps, opportunities, and challenges Open
Oil sands development in the Athabasca and Cold Lake oil sands regions of Alberta has raised concerns about potential impacts to groundwater and groundwater dependent ecosystems. This review summarizes the current state of understanding as…

Sulfate in streams and groundwater in a cold region (Yukon Territory, Canada): Evidence of weathering processes in a changing climate Open
Analyses of the sulfur (S) and oxygen (O) stable isotope ratios (δ34SSO4 and δ18OSO4) of dissolved sulfate in streams and groundwater in Yukon Territory (YT, Canada) indicates that the dominant source of this major ion is oxidation of sulf…

The acute toxicity of bitumen-influenced groundwaters from the oil sands region to aquatic organisms Open
The extraction of surface mined bitumen from oil sands deposits in northern Alberta, Canada produces large quantities of liquid tailings waste, termed oil sands process-affected water (OSPW), which are stored in large tailings ponds. OSPW-…

Preparative isolation, fractionation and chemical characterization of dissolved organics from natural and industrially derived bitumen-influenced groundwaters from the Athabasca River watershed Open
Recent analytical advances have provided evidence that groundwater affected by oil sands process-affected water (OSPW) is reaching the Athabasca River at one location. To understand and discriminate the toxicological risks posed by OSPW-in…

Ecological effects and causal synthesis of oil sands activity impacts on river ecosystems: water synthesis review Open
Oil sands development in the lower Athabasca River watershed has raised considerable public and scientific concerns regarding perceived effects on environmental health. To address this issue for tributaries and the mainstem of the Athabasc…

Non‐target profiling of bitumen‐influenced waters for the identification of tracers unique to oil sands processed‐affected water (OSPW) in the Athabasca watershed of Alberta, Canada Open
Rationale The objective of this study was to identify unique chemical tracers of oil sands process‐affected water (OSPW) to enable definitive discrimination of tailings pond seepage from natural bitumen‐influenced waters from the Canadian …

The Canadian Water Resource Vulnerability Index to Permafrost Thaw (CWRVI<sub>PT</sub>) Open
This study developed and applied a framework for assessing the vulnerability of pan-Canadian water resources to permafrost thaw. The national-scale work addresses a key, but neglected, information gap, as previous research has focused on s…

Advances in Distinguishing Groundwater Influenced by Oil Sands Process-Affected Water (OSPW) from Natural Bitumen-Influenced Groundwaters Open
The objective of this study was to advance analytical methods for detecting oil sands process-affected water (OSPW) seepage from mining containments and discriminating any such seepage from the natural bitumen background in groundwaters in…

Assessing Risks of Shallow Riparian Groundwater Quality Near an Oil Sands Tailings Pond Open
The potential discharge of groundwater contaminated by oil sands process‐affected water ( OSPW ) is a concern for aquatic ecosystems near tailings ponds. Groundwater in the area, but unaffected by OSPW , may contain similar compounds, comp…
